Abstract

This paper presents a method of fabricating photonic crystal fiber by secondary drawing technology combined with air pressure regulation. The internal structure of optical fiber is solidified and shaped by primary drawing. The core diameter of PCF is reduced to less than 4 μ m by adding glass sleeve in secondary drawing. Multi-core PCF is prepared, and the curvature and temperature of two-core PCF are measured. Fan-shaped PCF, band gap PCF, silver-filled PCF and V-shaped PCF are prepared, and the dispersion and loss of V-shaped PCF are simulated. The drawing parameters are fitted and compared. The parameter curve of furnace temperature presents an upward concave shape, and the parameter curve of air pressure threshold presents an upward convex shape. These fitting curves have reference value for the preparation of PCF in the future. • A method of preparing various PCFs by secondary drawing technology is proposed. • Various solid PCFs are prepared, and the core diameter is reduced to 4 um. • Two kinds of hollow-core PCFs are prepared. • Silver-filled and butterfly-shaped PCFs are prepared.
